Pear trees have strong stress resistance and wide adaptability, and can be cultivated on sandy land, mountainous land and hilly land. The planting soil is preferably a relatively fertile sandy loam with deep soil layers and good drainage. 1. Deep plowing of pear orchard soil Deep plowing can deepen the root distribution layer, make the roots develop deeper into the soil, reduce "surface-floating roots", improve drought resistance and absorption capacity, and has a significant effect on rejuvenating tree vigor and improving yield and quality. In production, the alternate-row deep plowing method is often used, and it takes 2 to 3 years to complete all the plowing; the ring-ditch method of expanding the planting hole can also be used. The deep plowing time is best completed before leaf fall in autumn,

Pear trees have strong stress resistance and wide adaptability, and can be cultivated on sandy land, mountainous land and hilly land. The planting soil is preferably a relatively fertile sandy loam with deep soil layers and good drainage.

1. Deep plowing of pear orchard soil

Deep plowing can deepen the root distribution layer, make the roots develop deeper into the soil, reduce "surface-floating roots", improve drought resistance and absorption capacity, and has a significant effect on rejuvenating tree vigor and improving yield and quality. In production, the alternate-row deep plowing method is often used, and it takes 2 to 3 years to complete all the plowing; the ring-ditch method of expanding the planting hole can also be used. The deep plowing time is best completed before leaf fall in autumn, which is beneficial to root healing and new root formation. Soil deep plowing is best carried out before and after leaf fall, with a plowing depth of 10 to 20 cm. The ditch width is 50 to 60 cm and the depth is 60 to 80 cm. Deep plowing combined with applying base fertilizer has a better effect. After plowing, do not harrow so as to facilitate soil weathering and winter snow accumulation. Plowing saline-alkali land has the effect of preventing salt return and is also beneficial for preventing overwintering pests.

2. Soil improvement

1. Improvement of sandy soil and clay soil. Pressing clay onto sandy land and mixing sand into clay soil can loosen the soil, thicken the soil layer, improve the soil, and enhance water storage and fertilizer retention capacity. It is an effective measure for soil improvement of sandy land and clay land. Increasing the application of organic fertilizer is also an effective measure for improving sandy land and clay land, and is beneficial to the growth and development of young trees.

2. Soil improvement of saline-alkali land. Measures such as building raised fields, introducing fresh water to wash away salt, planting green manure crops, ground mulching, increasing the application of organic fertilizer, and intertillage can effectively improve the physical and chemical properties of the soil and reduce the harm of the soil to young pear trees.
